초록

A filter apparatus includes a filter element. The filter element is formed of a sheet of gas-porous filter material which has been folded into accordian pleats. Alternate pleat-folds are of tight, near knife-edge definition, and arcuate form definition. Hence, all folds on one side of the accordian-folded material are of the knife-edge form, and all folds on the other side are of the arcuate. The pleated material is turned into a cylindrical conformation, with the arcuate folds confronting the central axis of the cylinder, and the tight, knife-edge folds...
